SPECIFICATION forming part of Letters Patent No. 508,361, dated November7, 1893.

Application' filed June 17l 1893.

To all whom it may concern.-

Be it known'that I, DAVID YOUNG, a citizen of the United States, and aresident of Anglesea, in the county of Cape May and State of New Jersey,have in vented certain new and useful Improvements in Sash-Locks orFastenfollowing to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make'and use the same.

This invention relates to sash-locks orfaswindows, and has for itsobject to provide a device of the character set forth which is strongand durable and will stand vibratory force and shocks or blows incidentto the jarring and jolting of a moving car without becoming injured orimpaired, and will thereby always insure a ready operation without theinconveniences and disadvantages usually attendant upon the fasteningsof car-windows. With these and other objects in view, the

rangement of the several parts as will be more fully hereinafterdescribed and claimed.

In the drawings: Figurel is a front elevation of a car-window frame andsash broken away at several points and showing the improved lock orfastener applied thereto. Fig. 2 is a section on the line Fig.4:,showing the lock or fastener operated to release the bolt for thepurpose of raising the sash. Fig. 3 is a view similar to Fig. 2 with thebolt in locked position. Fig. 4 is a transversevertical section on theline y-y Fig. 1. Fig. 5 is a detail perspective view of parts of thelock or fastener disassembled.

Similar numerals of reference are employed to indicate correspondingparts in the several figures of the drawings.

Referring to the drawings, the numeral 1 designates the sash framehaving the customary sash-grooves in opposite sides thereof in one ofwhich is formed a series of recesses 2 and thereover is fixed a metallicwear strip 3 having openings -i therein aligning with the said recesses2. The lower part of the right of the sash is provided with a mortise 5having a front opening 6 and at the edge is supplied with a bolt opening7. Over the said bolt SerialNo. 477.997- (No model.)

opening is mounted an escutcheon plate 8 having an opening thereinaligning with the said bolt opening 7 and acting tohold the bolt inproper position and take up wear.

ToV the outer lower side of the sash is secured a tubular sleeve 9having an inner integral collar l0 that bears against the sash and inadvance of the said collar the said sleeve is formed witha pair ofoppositely disposed lugs 11. Within the said sleeve 9 is located apushbar 12 having an outer shouldered collarI 13 .which is movablyfitted in the said sleeve and formed with an outer a'nged head 14provided with a milled edge, the said flanged head limiting the inwardmovement of the collar 13 and the push-bar l2. The push-bar 12 issurrounded by a coiled spring 15 which has its inner end bearing againstthelugs l1 and its outer end against the shouldered collar 13, thenormal tendency of the said spring being to force the said collaroutwardly as will be readily understood. Pivotally mounted between thelugs 11, is a bell-crank lever 16, having a cam-arm 17 with a stud orpost 18, rising therefrom, and a cam-lug 19 in rear of the said stud orpost. VThe other arm, 20, of the said bellcrank lever is formed of aboutthe same thickness as the greater part of the said cam-arm, and issupplied with an opening 21 near the end thereof. The elbow of the saidlever has an opening 22 therethrough throu gh which eX- tends a rigidlymounted pin 23, whose opposite ends are secured in the said lugs 11 andon which the bell-crank lever freely turns. The inner end of thepush-bar l2 is iiattened and formed to somewhat resemble a cam to engagethe curved edge of the cam-lug 19 which is adjacent thereto for thepurpose of properly operating the bell-crank lever. The said inner endof the push-bar is formed with an opening 24, through which the stud orpin 18 passes to provide a pivotal connection of the two parts.

To the arm 20 of the bell-crank lever is pivotally connected the innerbifurcated end 25 of a slide-bolt 26, the said slide bolt being normallydisposed in a plane at a right angle to the plane of the push-bar l2,and has its outer end beveled as at 27 for evident and wellknownpurposes.

in the opening 7 of the sash and is adapted to IOC This slide-bolt ismounted have bearing in the escutcheon 8, andengage the recesses 2 forholding the sash in its adjusted position. When the collar 13 and head14 thereof are free to be iniiuenced by the spring 15 the bolt 26occupies a normal locked position, as the said spring exerting its forceon the push-bar 12 through the collar 13draws the cam-arm l7 of thebell-crank lever outwardly and through the arm 2O of said lever towardthe sash frameand consequently moves the slide-bolt in a similardirection. By the intervention of the said bell-crank lever it will beobserved that the spring 15 is caused to act reversely on the slide-boltin view of the operation of springs of a similar character usuallyemployed with sash-locks or fasteners for car-windows. On pressing thepush-bar 12 inwardly as shown in Fig. 2 the adjacent bearing edge of thecam-lug 19 is engaged firmly by the inner end of the said push-bar andthe beILcrank lever is thereby operated on its pivot to move the arm 20backwardly from the sash-frame and retract the slide-bolt 26 to permitthe sash to be raised. The provision of the cam-lug relieves the stud orpost 18 of a part of the wear and tension which would otherwise bebrought to solely bear thereon. It will also be seen that in raising thesash the sleeve 9 may be eiectually used as a grip in addition to theordinary linger `grip which will be provided as shown in Fig. l, and themovement of the operator to release the slide-bolt, being an inwardpush, instead of an outward pull, the sash may the more readily andquickly be raised.

While the device is shown applied to a car- Window, it will beunderstood that it can be as readily employed in connection with anyother form of sash and in all forms of application thereof, such changesthat lie within the scope of the invention together with a Variation inthe proportions might be made and substituted for those shown anddescribed without in the least departing from the nature or spirit ofthe invention.`

Having thus described the invention, what is claimed as new islIn a sashlock or fastener, the combination of a spring actuated push bar, a slidebolt disposed at a right angle thereto, and a bell crank lever connectedto the inner end of said slide bolt and push bar, and having aprojecting cam lug with which the inner end of said bar is adapted toengage said cam lug, being located on the outer side of the bell cranklever having its bearing edge corresponding in contour to the inner endof the push bar, substantially as described.

In testimony whereof Il have signed this specification iu the presenceof two subscribing witnesses.
